   = help: items from traits can only be used if the trait is implemented and in scope
   = note: the following traits define an item `is_empty`, perhaps you need to implement one of them:
           candidate #1: `std::iter::ExactSizeIterator`
           candidate #2: `core::slice::SliceExt`
           candidate #3: `core::str::StrExt`

error: aborting due to previous error
